Relative dating (steno's laws): long before geologists tried to quantify the age of the earth they developed techniques to determine which geologic events preceded another, what are termed relative age” relationships. Geologic time scale: precambrian period relative dating puts the events in sequential order (or for any of the geologic history of earth. Essentially, relative dating is the determination of the order in which a sequence of geologic events occurred understanding the relative time of these events helps geologists to interpret geologic history the ability to interpret geologic history has enabled geologists to develop a more precise geologic time scale. Activity 7: relative dating the geologic time scale was initially developed by determining the relative ages of rock units, first in europe, and then in other parts of the world most of this work was done in the 1700s and 1800s.

Relative dating planets relative and absolute ages in the histories of earth and the moon: the geologic time scale. Measuring the amounts of radioactive elements in rocks let scientists useabsolute dating to give ages to each chunk of time on the geologic time scale for example, they are now able to state that the jurassic began about 200 million years ago and that it lasted for about 55 million years.
